Definitions

  • Figure 3 is a plan view of the ring nest members (quadrant plates).
  • Figure 6 is a plan view of the ring knife member.
  • Figure 15 is a diagrammatic view of the control system of the piston ringing apparatus of Figure 1.
  • the rail rings typically comprise spring steel.
  • Each piston P is fixtured by suitable fixture members 4 on a pallet PL that is mounted on a slide 6 that, in turn, is transported on a piston carousel 8.
  • the fixture members 4 engage and fixture the connecting rod CR connected to the piston P to position the piston P in an inverted orientation as shown.
  • the piston carousel 8 traverses past the piston-ringing apparatus (station) shown in Figure 1 via upper and lower cam followers 10a, 10b.
  • Each slide 6 is movable downwardly to allow the piston thereon to be lowered to a first rail ringing apparatus for assembly of the first rail ring RR into the piston groove 7 on one side of the expander ring ER in manner to be described.
  • the piston P is moved to a second rail ringing apparatus like that used for assembly of the first rail ring RR for assembly of the second rail ring RR on the other side of the expander ring ER.
  • the slide 6 is transferred to a partial rail section (not shown) that is contiguous with rail PR and is lowerable/raiseable by a conventional pneumatic actuator (not shown) to effect piston ringing and then raising of the ringed piston for conveyance on rail PR to the next ringing station.
  • the ringing apparatus for assembling the first (upper) rail ring RR in the piston groove 7 on the upper aide of the expander ring ER is shown.
  • the apparatus for assembling the second (lower) rail ring ER on the lower side of the expander ring ER in groove 7 is identical with one minor exception to be explained below.
  • the terms upper and lower are relative to the piston P while held in the inverted position shown.
  • Each successive lowermost ring RR on the cartridge 10 is knifed laterally from the ring stack and transported to a plurality (four shown) of ring nest members 22, 23, 24, 25, Figure 3.
  • the base 14 includes four carbide inserts 30 on which each ring RR is slid to the nest members 22-25.
  • the carbide inserts extend on the base 14 toward the nest members 22-25 to provide high wear resistant surfaces to resist wear and abrasion as the rings RR are transported from the cartridge 10 to the nest members 22-25.
  • each nest member 22-25 comprises first and second plates 22a, 22b; 23a, 23b; etc. spaced apart by a spacer 15 in the direction of the axis V so as to define a fixed axial dimension, D, therebetween.
  • the nest members 22-25 are recessed as shown in Figure 3 to form an elongated ring-receiving recess 50 having an open end facing the cartridge 10 and aligned with a channel 51 formed between other spacers (not shown but held between the base 14 and base cover plates 14c, 14d) to receive each ring RR transported from the cartridge 10 to the nest members when they are in the contracted positions of Figure 4.
  • the ring nest members 22-25 are movable in unison from the radially contracted positions to radially expanded positions when the rail ring RR received in recess 50 is expanded concentrically about axis V so as to collectively form a second, radially larger circular opening for receiving the piston P to be ringed.
  • the nest members 22-25 are biased by respective springs S2-S5 in a direction toward the axis V.
  • radial expansion of the ring RR in the recess 50 causes the nest members 22-25 to expand radially outwardly in unison on slides 32-35, compressing the springs S2-S5.
  • Springs S2-S5 are disposed between a respective fixed member M2-M5 and the respective slide 32-35, see Figure 4 for spring S4.
  • a cam follower 69 on eccentric arm 77 and cam rotary actuator 72 are associated with each pair of overlapping arm ends 60b, 62b and 63b, 64b such that rotation of the cam followers 69 and arms 77 by the actuators 72 will cause the arms 60, 62 and 63, 64 to move outward and cause the nest members 22-25 to move outwardly on their slides 32-35 beyond the expanded positions after the ring RR is installed in the groove 7 of the piston P. This outward movement of the nest members 22-25 beyond the expanded positions permits ready removal of the ringed piston P as will be explained further below.
  • a ring knife means 70 is provided for movement in the groove 20 to this end and comprises a first slide member 71 (bearing blocks available from IKO International, Inc., 20-F Chapin Road, Pine Brook, NJ 07058) reciprocable on slideway 74 (also available from IKO Corporation) from the start position ST in a first direction toward the first recess 50 and a second direction away from the first recess 50 back to the starting position ST.
  • the slide member (bearing block) 71 is connected via bracket 71a to the rod 76a of pneumatic cylinder 76 mounted on the apparatus base 18.
  • a riser member 79 having an inclined ramp is attached on slide member 71.
  • An intermediate bearing block 78 is fastened on the riser member 79. Movable on the bearing block 78 is a slideway 80 that is mounted to wedge 81 (slideway 80 and bearing block 78 comprising a second slide member). The slideway 80 thereby is inclined in a direction from the start position ST toward the recess 50 (i.e. oblique to the horizontal direction of movement of slide member 71).
  • the wedge 81 is connected to the rod 84 of fluid cylinder 86 so as to be movable with slideway 80 on intermediate bearing block 78.
  • the cylinder 86 is mounted fixedly on the first slide member (bearing block) 71.
  • a knife member 90 is disposed on the second slideway 80.
  • the knife member 90 comprises a carbide insert 92 fastened by screw 92a to the knife extension 94, which contains a carbide wear strip 94a, the whole of which are attached to wedge 81 by screws 94b.
  • a thin guide blade 93 is disposed forwardly of the insert 92.
  • the knife member 90 is positioned to place the insert 92 in a raised, ring knifing position KP relative to the first slide member 71 in order to remove the lowermost rail ring RR from the cartridge during knife movement from the start position ST toward the nest members 22-25.
  • the knife member 90 is raised relative to the first slide member 71 (bearing block) by movement of the wedge 81 using cylinder 86. That is, the cylinder 86 moves the wedge 81 and inclined slideway 80 to the raised, ring knifing position KP on intermediate bearing block 78.
  • the insert 92 of the knife member 90 will engage and remove the lowermost ring RR on the cartridge 10 when moved from the start position ST toward the nest members 22-25. That is, the lowermost rail ring RR is disposed between the bottom of the cartridge 10 and the base 14 in the path of the raised knife insert 92 as it is moved toward the nest members 22-25.
  • the thin, elongated ring guide blade 93 is received in the slit S of each rail ring RR removed from the cartridge 10 to maintain the same ring orientation as present on the cartridge; i.e. the slit of the ring RR faces the recess 50 defined by the nest members 22-25.
  • the guide blade 93 is fastened to the wedge 81 by screws 96.
  • the knife member 90 is moved by the cylinder 76 to a ring insertion position where the removed ring RR is positioned in the first recess 50 coaxial with the axis V defined collectively by the nest members 22-25 in the contracted positions.
  • the ring insertion position is controlled by a stroke control mechanism 200 described below.
  • the presence of a rail ring RR in the recess 50 for assembly in the piston groove 7 is verified by a fiber optic sensor 130 incorporated in nest member 23, Figure 10.
  • the knife member 90 is moved to a lowered position relative to the slide member (lower bearing block) 71 by movement of the wedge 81 using cylinder 86.
  • the cylinder 76 is actuated to return the knife member 90 to the start position ST.
  • the knife member 90 is moved to a lowered position prior to actuation of cylinder 76 so that it can be returned to the start position ST without the insert 92 and guide blade 93 striking the bottom of the stack of rings RR on the cartridge 10.
  • the above-described movement of the knife member 90 between the start position ST and the lowered position is repeated for each successive rail ring RR removed from the cartridge 10 and positioned in the recess 50.
  • a locating annulus 127 is fixedly disposed on the finger support member 122 and includes a plurality of piston locating extensions or flanges 129 that extend radially inward between the spaced apart ring expanding fingers 100 as shown best in Figures 9 and 10. Since the fingers 100 and the annulus 127 are mounted on the support member 122, they move in unison therewith along the axis V. As will be explained below, the piston locating flanges 129 initially support the piston P to locate the piston groove 7 out of alignment with the expanded ring RR residing in the enlarged second recess defined by the expanded nest members 22-25.
  • the finger support member 122 is disposed on a vertical slide member 125 that is attached on a vertical slideway 126 which is disposed in a bearing block 126a for movement in an up/down manner.
  • the bearing block 126a is mounted on a frame 128 mounted on apparatus base 18.
  • Beneath the vertical slide member 125 is a stop member 130 on a lift plate 142 and disposed to slide along the vertical slideway 126 by means of a second bearing block 126b.
  • the stop member 130 is held in an adjusted or selected position by bracket 131 and adjusting screw 133, Figure 8.
  • the slide member 125 is separated from the stop member 130 by a pair of springs 132 that bias the slide member 125 in an upward direction to locate the fingers 100 in an initial, predetermined position relative to the recess 50 and the unexpanded rail ring RR therein.
  • the finger support member 122 is positioned a predetermined distance X above the stop member 130 such that the finger support member 122 can be moved downwardly a predetermined distance until it abuts the stop member 130.
  • the slide member 125 is moved vertically up/down by a lift member 140 comprising a lift plate 142 disposed beneath the slide member 125 on slideway 126, a cam follower 146 attached to the lift plate 142, and a cam track 144a in a cam plate 144 disposed in a slide mounted to the frame 128 mounted on apparatus base 18 and bracket 18a, as shown best in Figures 7 and 8.
  • the cam plate 144 and its cam track 144a are moved past the cam follower 146 by the rod 148 of a pneumatic cylinder 150 disposed on a frame mounted on apparatus base 18.
  • cam follower 146 rides in the cam track 144a and moves the attached lift plate 142 vertically. Movement of the cam plate 144 and cam track 144a to the right in Figure 7 raises the finger support member 122 and the fingers 100 thereon into the opening 49 with the ring RR residing in recess 50. Movement of the cam plate to the left in Figure 7 lowers the finger support member 122 and fingers thereon out of the ring RR and the opening 49.
  • the ring expanding fingers 100 are also disposed for radially outward/inward movement relative to axis V.
  • the fingers 100 are mounted on finger support blocks 124 each including a cam rail 124a that inclines from the center toward the circumference of the circular block array.
  • Each cam rail 124a is adapted to be engaged by camming surface 152a of cam member 152 centrally disposed of the fingers 100. That is, the cam member 152 is movable on an axis that is coaxial with the axis V.
  • the cam member 152 is movable along axis V via an axial, knobbed shank 152b that is connected to a rod coupling 158 of fluid cylinder 160, Figure 7.
  • the ring expanding fingers 100 are raised/lowered and radially expanded/contracted relative to the recess 50 and the unexpanded rail ring RR residing in the recess 50.
  • the apparatus includes means for positioning the piston groove 7 at a ring receiving position relative to the expanded ring RR residing in the enlarged recess 50 formed by the expanded nest members 22-25.
  • the locating annulus 127 (fixedly disposed on the finger support member 122) includes a plurality of piston locating extensions or flanges 129 that extend radially inward between the spaced apart ring expanding fingers 100 as shown best in Figures 9 and 10.
  • the fingers 100 and the annulus 127 are movable in unison along axis V as a result of being mounted on the support member 122.
  • the piston P is lowered along axis V with the dome end DP facing down to position the dome end DP in the enlarged recess 50 (defined by the expanded nest members 22-25) in engagement with the locating flanges 129 as illustrated in Figure 13. As shown, this engagement initially locates the piston groove 7 above and out of axial alignment with the expanded ring RR residing in the enlarged recess 50. As is apparent, the bottom of the groove 7 formed by the expander ring ER is level (coplanar) with the upper ends of the fingers 100.
  • This distance X is predetermined to axially align the upper ends of the fingers 100 with the bottom of the enlarged recess 50 of the expanded quadrant plates 22-25 so that the recess 50 and expanded ring RR therein, in effect, communicate to the piston groove 7 and allow the expanded ring RR to snap into the now axially aligned groove 7 above the expander ring ER already in the groove 7.
  • This axial alignment is shown in Figure 14.
  • the rotary actuators 72 are actuated to move cam followers 69 relative to the overlapping arm ends 60b, 62b and 63b, 64b such that the arms 60-64 move outward and cause the nest members 22-25 to move outwardly on their slides 32-35 beyond the expanded positions.
  • This outward movement of the nest members 22-25 beyond their expanded positions permits ready removal of the ringed piston P from the nest members 22-25 by upward movement of slide 6.
  • a similar ringing apparatus is used to position the lower rail ring in the piston groove 7 above the expander ring ER.
  • the term "lower” is used here with respect to the inverted piston P. This rail ring actually is above the expander ring when the piston is assembled in the engine.
  • a stroke adjustment mechanism 200 is provided for the knife member movement mechanism to control the stroke of the rod 76a of the cylinder 76 in a manner that the larger diameter rail ring will be positioned in the recess 50 concentric about the axis V.
  • the slide plate 216 positions a stroke control flange 215 fastened on the plate 216 in the path of a stop bracket 218 of the bracket 71a to abut the bracket 218 to provide a particular ring insertion position for larger diameter rail rings.
  • Eccentric movement of the cam follower 212 is controlled to slide the slide plate 216 to withdraw the stroke control flange 215 out of the path of the rod bracket 218 to provide a second ring insertion position for the smaller diameter rail rings to insure each ring is positioned in the recess 50 concentrically of the axis V.
  • nest members 22-25 are carried on the slides 32-35, they can expand radially with the ring residing in the recess 50 sufficiently to accommodate its expansion to enlarged assembly size.
  • the rotary actuators 72 and cam followers 69 provide enough stroke to expand the rest members 22-25 for clearing either a small or large size piston and rings assembled thereon. No adjustment thereof is required.
